Prevention of the five major faults that often occur in skf bearing operation
SKF bearings exhibit strong regularity during their use and are very repeatable. Normal high-quality stainless steel bearings have relatively small vibration and noise at the beginning of use, but the spectrum is somewhat scattered and the amplitude is small, which may be due to some defects in the manufacturing process, such as surface burrs.
After a period of exercise, the vibration and noise are maintained at a certain level, and the spectrum is very single, only one or two times the frequency appears. There are very few spectrums above the power frequency, and the stainless steel bearing state is very stable and enters a stable working period.
After continuing to run, the vibration and noise of the SKF bearing begin to increase, and sometimes abnormal sound occurs, but the vibration increases to an initial failure.
First, the spectral analysis of the bearing found that the concentration of non-ferrous metal elements was abnormal, and many sub-micron wear particles of non-ferrous metal components appeared in the iron spectrum; the moisture content of the lubricating oil exceeded the standard and the acid value exceeded the standard, indicating that the tile surface of the SKF bearing was corroded.
Second, the bearing spectrum analysis found that the iron concentration was abnormal. There were many sub-micron wear particles in the iron spectrum. The moisture and acid value of the lubricating oil were abnormal, indicating that the bearing back was worn due to fretting.
Third, there are iron-based abrasive grains or black oxide particles in the iron spectrum of the stainless steel bearing, and there is a tempered color on the metal surface, indicating that the journal surface of the bearing is strained.
Fourth, the cutting abrasive grains were found in the iron spectrum of the SKF bearing, and the abrasive grain composition was non-ferrous metal, indicating that the surface of the bearing was strained.
Fifth, the bearing spectral analysis found that the concentration of iron was abnormal. There were many submicron particles of iron in the iron spectrum. The moisture content of the lubricating oil exceeded or the acid value exceeded the standard, indicating that the journal surface of the needle bearing was corroded.
Now that we know the cause of the SKF bearing failure, then we mainly pay attention to these aspects, and the service life of the stainless steel bearing will naturally be long.
When the external hard particles enter the bearing and press between the body and the raceway, the surface can be indented. In addition, an excessive impact load can also cause local plastic deformation of the contact surface to form pits. When the SKF bearing is stationary, even if the load is small, evenly distributed pits will be formed on the raceway due to vibration of the surrounding environment.
When the SKF bearing seal is not good, dust or particulate matter enters the bearing, or the lubrication is poor, which will cause serious scratch or wear on the contact surface and increase the vibration and noise of the stainless steel bearing.

Talking about: bearing characteristics of rolling mill
The roller and the raceway are in contact with the wire or repaired, and have a large radial load capacity, and are suitable for bearing heavy loads and impact loads. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.
It can move axially and can adapt to the change of the relative position of the shaft and the shell caused by thermal expansion or installation error. It can be used as a free end support.
The machining requirements of the shaft or the seat hole are relatively high, and the relative deflection of the outer ring axis after the bearing is installed must be strictly controlled to avoid contact stress concentration.
The inner or outer ring can be separated for easy installation and removal.
For steel stamping cages, for high-speed bearings or for bearings that require smooth operation, solid cages are used. Depending on the application and the user's requirements, cages with fiberglass reinforced plastics can also be designed and supplied.
